State Park (I think that's the one...?)
Years ago (1980's) I attended a Czech film festival held in Ottawa, Canada because one of the films had as an integral part of the plot a school orienteering team going to a competition or series of competitions. I don't remember much about the film but for my taste there was too much human drama and not enough actual orienteering scenes. However it was still gratifying that somewhere in the world someone had made a movie with orienteering as a backdrop.
